I 1 I, It =is.also preferable ito provide a similar double In Figure l' is shown a conventioried motor hinged connection 36 between the .hood and the .xhood:comprislng a substantiallyvertical -sideporclosure member at the dipper andl'lower iSidBSzOf izionrl'o andaicurvedupper portion111, these-porthe latter, rthese hinges being constructed in-a mtioasgbemihimfiiflflmfitedu J2 -:to permit tmannersimilariitolthat employed in theforward retained on the spindle by and rearward hinges hereinbefore described with the exception that the hinge may be relatively short.

From this construction it is apparent that the closure member is supported for bodily movement from closed to opened position outwardly of the opening 15 and remains at all times substantially parallel to the side of the hood, thus afiording an adequate clearance entirely around the opening whereby air entering through the radiatorat the forward end of the vehicle may be readily discharged.

The closure member is preferably manipulated to any desired position and retained therein by means of an operating handle 40 journalled in a bushing 41 which rotates about an axis substantially perpendicular to the hood, the hood being oifset inwardly as indicated at 42 in Figure 2 of the drawings to receive the spindle 44 of the operating handle, bushing 41 being retained in position by means of an annular plate '45, the parts being welded together if desired.

At its inner end the spindle is provided with a reduced. portion 48 to which is keyed or other- .wise. secured a crank disc or crank arm 49.

The disc/49 is threaded to receive a pair of pivot pinsfildisposed on opposite sides of the spindle 44, .each. of which passes through an eye in one end.of .a link 52, thus affording an nular flanged portion overlying the ends of the links 52 to ensure-retention of the latter iniposition on the pins .51, the bushing being in turn means of a washer 55 and cotter pin 56.

The opposite end of each of the links 52 is connected to the double hinge at the corresponding end of the closure member, this connection being preferably effected as shown in Figures 3 and 4 in which an arm 60 is welded or otherwise secured to the arm 30 of the hinge and is provided at its free end with a hinged connection to the link 52.

vIt will be observed that when the handle 40 is rotated, the resulting rotation of the crank disc 49 will serve to simultaneously draw each of thelinks 52 toward each other and will thus move the associated free end of the arm 60 toward the central portion of the hood. This movement of the arm 60 toward the dotted line position in Figure 3 serves to move the arms 27 and .30, which form in effect a toggle, toward a straightened position andthe extension of this toggle shifts the closure member bodily outwardly of the opening in the hood. It will be noted that by reason of the connection between the links 52iand the crank disc, the closure member is. positively locked in either the closed or the entirely opened position since any force acting on the closure member and transmitted through the links 52 will be directed through the axis of the spindle 44.

Having thus described theinvention, what is claimed as new and desired to be secured by Letters Patent is:

1. In a motor vehicle, the combination with an. engine hood having a ventilating opening therein, of a closure member for said opening,

hinge connections being reversely disposed, and

a common operating means vfor simultaneously flexing said hinge connections.

. 7. In a motor vehicle, the combination with an engine hood having a ventilating opening in the side thereof, of a closure member for said .opening, and means for supporting said closure member for bodily movement toward and away from said opening, said means including a double hinge connection between said hood and said closuregmember, said double hinge connection j comprising .apairof. members having pivotal connection with each other and with the closure member and hood respectively.

8. In a motor vehicle, the combination with an engine hood having a ventilating opening in the side thereof, of a closure member for said opening, and means for supporting said closure member for bodily movement toward and away from said opening, said means including a plurality of double hinged connections between said hood and said closure member located at opposite sides of the latter, each hinge connection comprising a pair of members having pivotal connection with each other and with the'closure member and hood respectively.

9. In a motor vehicle, the combination with an engine hood having a ventilating opening in the side thereof, of a closure member for said opening, means for supportingsaid closure member for bodily movement toward and away from said opening, said means including a plurality of double hinged connections between said hood and said closure member located at opposite sides of the latter, and means operatively connecting said hinged connections to constrain the latter 'to movement in unison.

10. In a motor vehicle, the combination with an engine hood having a ventilating opening in the side thereof, of a closure member for said opening, means for supporting said closure member for bodily movement toward and away from said opening, said means including a plurality of double hinged connections between said hood and said closure member located at opposite sides of the latter, and operating means associated with said hinged connections for manipulating the latter to position said closure member.

11. In a motor vehicle, the combination with an engine hood, having a ventilating opening in the side thereof, of a closure member for said opening, means for supporting said closure member for bodily movement toward and away from said opening, said means including a plurality of double hinged connections between said hood and said closure member located atopposite sides of the latter, operating means associated with said hinged connections for manipulating the latter to position said closure member, said operating means comprising a rotatable element, and link members having articulated connection with said hinged connections and said rotatable element.
